So basically we're saying yes, we can go from point a to point c without ever going through point b.
所以我们说的是我们可以从,a点不经过b点而到达c点。
We take, um, legislation and regulation, which is sort of how our agencies work in Washington D.C.,
我们还学习立法和规章,学习华盛顿特区的政治部门是如何做这些工作的,
So we can figure out the energy of each photon emitted by our UV lamp by saying e is equal to h c over wavelength.
所以我们可以计算出,每个从紫外光源射出的光子,也就是e等于h乘以c除以波长。
We'd expect you to write now or perhaps ever since this program was written as part of an obfuscated C contest.
我希望你们现在就开始写程序,否则你们将会在C语言比赛中,写得非常糟糕。
c That is why we have one. That's why we have c.
这就是为什么我们有了符号。
OK, and if I wanted to look at it, we can come back over here, and we can see what does c p 1 look like, interesting.
现在对于这里的每个实例,我都赋了x和y值,好,那么如果我想要研究下它,我们可以回到这里来。
We can't go C, D, D-sharp, F.
不能是C,D,升D,F
But now, imagine that we are living in the early years of a polis sometime in the eighth century B.C.
但是,现在想象一下,假如我们生活在公元前八世纪
Well,that's why we said up here that in Phase C when there's a corpse,I don't exist.
所以我们说在C阶段作为尸体,我并不存在。
We'll assume that constant marginal cost just as it was last time is equal to C.
我们假设固定边际成本,像上次一样等于C
So, let's just arbitrarily put it between these two in this case here, but actually there's no reason we couldn't also put it between oxygen b and c, so I'm going to draw another structure where we have it here.
那么,让我们任意地将它们放在这两个之间,但实际上我们没有理由,不能把它们放在氧原子,B,与,C,之间,因此我将把另外一个结构画在这里。
And I picked looking at methane so we could see if there are other factors that we're not considering, that we need to maybe tweak our model a little bit, and I think we'll find that we do if we take a look at a polyatomic molecule, methane, CH4 so c h 4.
我选择甲烷这个例子,我们可以看到,如果有一些我们没有考虑到的因素,我们需要修改一下我们的模型,我们看一看,甲烷CH4这个多原子分子,就会知道这一点,甲烷。
And we give different names, depending on what kind of electrons we're dealing with, so, for example, with h c l here, we can talk about having bonded versus lone pair electrons.
我们还起了不同的名字,给我们要处理的不同类型的电子,以氯化氢为例,我们来介绍一下成键电子与孤对电子。
We somehow have to take hydrogen, attach it to carbon, and we have to make it symmetric, and we have to make it nonpolar.
我们需要把H接到C周围,而且我们需要让它是对称,且非极性的。
So we are actually using the C99 version of C, which really means nothing useful today other than to realize we are using that version.
所以我们在使用的C语言的C99版本,这对今天来说是没多大用处的,只是告诉我们使用的是那个版本而已。
Here for example we have the pitch C and either note above or below it is dissonant.
如果说这里用C音,那么不管是和它上面还是下面的音符搭配都不和谐。
